Nothing, it is free.
Definitely no, Trabber is just a comparison site. Every flight that Trabber finds has a direct link to the web page where you can buy the ticket at the same price as if you had directly searched it there. In addition in some cases you will even find in Trabber prices which are cheaper than those you can get by going directly to a website. This happens because some sites apply special discounts to Trabber users because they know they are being compared and they prefer to reduce their prices to sell more.
We are constantly adding new travel web sites. Currently, we do search on airlines, low cost companies and in the main online travel agencies of each country.
Trabber should always find all the flights with the cheapest price. When comparing take into account that Trabber considers all the fees and our prices are always final. If you have find a flight which is not shown in Trabber or has a cheaper price in another web please contact with us and we will add it to Trabber.
Each time that you do a search, Trabber engine starts making online connections to each one of the supported websites looking for flights according to your search criteria. Search is made like you would do it using a browser, and this is why Trabber results are the same that you would get by directly going one by one to all the webs. The difference is that, with Trabber, you only have to search once to find all the available flights.
Please, contact with us and we will investigate it.
